    Error Cannot implicitly convert type 'Umbraco.Core.Dynamics.DynamicNull' to '...' when render partial

    Hi, I have issue with rendering of a partial view Header. I have a controller which is incherited from SurfaceController.

       // GET: Header
    public ActionResult Index()
    {
        var content = Umbraco.Content(1054);
        Header viewModel = content.MapTo<Header>();
        return PartialView("Header", viewModel);
    }

    When I try to MapTo it gives me an error Cannot implicitly convert type 'Umbraco.Core.Dynamics.DynamicNull' to 'FormsWorkflow.UmbracoPortal.Models.Pages.Header'. Content contains properties list with my component. Can you please help..What is wrong?

    Hi Karie

    What is 'Header' type in your code?

    Umbraco.Content(1054) returns dynamics, it's definitely can't be a 'Header', so this code is wrong

    Thanks,

    Alex

    Hi Karie

    Use TypedContent, have a look - https://our.umbraco.org/documentation/reference/querying/umbracohelper/#typedcontent-int-id
